Suspension compressor fault
Morning Folks.
As always any advice greatly appreciated.
07 plate 90k
Refurbished compressor 3 years ago along with new 60 amp fuse and new relay.
Over the last couple of week I have started getting a suspension fault amber warning light, generally about 6/7 mile into my journey. Unfortunately on Sunday this then became 20/30 seconds after starting the car. I can hear the compressor running but as I said after 20/30 seconds then cuts out.
The old girl is sat very low with no air in the system.
Any ideas folks?
If air bags is there any way of pinpointing the affected corners?
Many thanks.

If you have access to an iid that will help you having to do a lot of guess work..
my initial thought, if its not an air bag, would be a valve block issue perhaps... check the front one in the offside wheel liner area and then check for worn wires at the bulkhead on the same side..
If you had an old Hitachi compressor the desiccant powder can get into the valve blocks and make them stick. I mention it only as you had a new compressor..
a search on the forum will throw up a lot more info and many solutions... but most will start with... use diagnostics.....1 TR6 Rusting away quietly

Cheap test's:
-Spray soapy water to the air bags, pipe connections, air tank and look for bubbles (use offroad height)
-Check air compressor pipings. Before i replaced mine (Hitachi) i had lots of wear in the air pipes close to the compressor.
None of them? Then valve block.Land Rover Discovery 3 2006 HSE 2.7 Zermatt Silver

Check for crack between where the two pipes go into the compressor - known problem with plastic plates

Soapy Water Fail
I used lots of soapy water on the struts and nothing ever showed. When replacing all of the struts the front right obviously was the problem.
Even puling the #3 fuse didn't help find the leaking bag. If you can get the IID tool, it gives you some good info about faults, then these can be closer diagnosed. My compressor had worn out exhaust valve seals, and was leaking prior to the strut. I had to get a quick fix as I work out of town the a new compressor was here faster than the exhaust valve kit.
In some cases the fault codes lead you right to the solution, in my case that didn't work this time.
If you can spend the cash the IID tool is a good investment, i'd say a necessity that pays for itself in parts chasing and dealership costs.
I've fixed many suspension issues on mine as the 2005 115K rover had some age to it, like myself. Post the faults here and someone will come along with the answer. These guys/gals have helped me save thousands of dollars and weeks of time fixing my issues. I now have rebuilt all valves, have three spare valves now, two old spare shocks and will be rebuilding the compressor to replace the cheap had to get her going compressor I picked up if a compressor code comes up.
Just pulling and cleaning the valves may do the trick, but o-ring kits are cheap and the repairs are well covered on u tube. Check out 4x4airseals, for orings and how to videos.2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

Thanks folks for all your words of wisdom.
Update.....got a friend to pop round with his snapon device which gave me some codes, cant remember them off hand. The next day I took the Disco out to put fuel in...strangely the suspension took air to full running height, only as I was reversing back into the drive did I get the suspension fault light on again.
I was then away for a few day's....only to find on my return the Disco sat at full height, I've had her out a couple of times since after a while the suspension fault light does come on but, I have been able to raise lower and drive as per normal for a spell.....
Correct me if I'm wrong but what I'm taking from this is air bags are good holding air and all plumbing must be good also along with compressor working, which hopefully makes the fault a little easier to diagnose.
Cheers

C1A13-64 Sound Familiar
Sounds to me like it is either the exhaust valve solenoid seals or a air dryer issue.
Depending on the Fault code, but if its C1A13 or C1A13-64, Gallery pressure fault, it could be the seals in the exhaust valve that is the 4 screw plate on the compressor.
If you look on here do a search for C1A13-64, or suspension diagnostic codes, someone has posted the diagnostic troubleshooting manual, which lists all / most of the suspension fault codes and some fixes for those issues. Anytime having codes read take note of any codes write them down and if you find this manual on here you can fix or troubleshoot things quite easily.
This is how mine started acting up last year when the weather went from fall to winter, I thought it was moisture in the system but it was the exhaust valve solenoid chamber and plunger needed new seals. As I did not have the seal kit, I took it apart and cleaned it of any white powder (Disco Cocaine) and put some o ring lube on all the seals and buttoned it back up. It worked until the seals wore out eventually and so I rebuilt it with the kit that I got from 4x4airseals. While you have the compressor out replace or renew the desiccant in the dryer, there are kits all over shebay for that. The plastic top on the dryer also has a tendency to crack between the fittings, so I got a Steel one from Lucky8 off road and replaced that as well. Saves time and effort later on.
This C1A13 seems to be a reoccurring issue on the Hitachi compressors, so if its that code, simply remove compressor and rebuild the exhaust valve and plunger. Try not to let the top o -ring come out of its groove as they are a bitch to get back in. If it does come out, use some o-ring lube or regular grease, coat the o ring with this and put it back in. The grease helps hold the o-ring in the groove long enough to get the cap back on.
Good Luck, do something now or you will get the Red Rocking Rover and then be in more trouble for driving it home.2005 Land Rover D3, 4.4L V8, Maya Gold Metallic

Hey folks.
I think we may have found the problem.
I had ordered the oring kit and had set about doing the valve block's today as a process of elimination, when I took off the plastic compressor guard it was soaking wet inside so decided just to take the compressor off for a bit of a look, plus the valve block located next to the compressor, when disconnecting the pipes there was a lot of moisture showing in the block. The attached picture was the outcome of stripping down the compressor.
Can anyone advise if there is a repair kit for this air dryer or what is the best route to go down for getting the old girl back on the road?
Cheers
Kenny
